Benefits of technology

The patent describes a pivot latch mechanism for a shoe, which can be a two-stage bayonet latch. The mechanism has a button that can be pressed to release the shoe. The button is on the side of the shoe, making it difficult for it to be accidentally pressed by the wearer's heel. This design prevents the button from being pressed when the shoe is being worn.

Problems solved by technology

It is problematic that the intermediate heel may wear and so also affect dimensional tolerances with resulting play in the extended heel.
The pivot mechanism is also difficult to operate.
Here the walking heel is not concealed, which is problematic in the sense that wear on the walking heel is unsightly in the high heel configuration.
The pivot mechanism is also cumbersome to use.
Also, where the ground contacting surfaces of the heel may be subject to unsightly wear, various heel pivoting configurations are able to hide or conceal the top caps or ground-contacting surfaces heel of the heel.

first embodiment

[0026]FIG. 1 shows a dual use shoe 100 according to a The shoe 100 has an upper 102 including a vamp 104 and a heel section 106 that are each attached to a sole 108. The upper 102 generally conforms to the contours of a human foot when the shoe 100 is placed on the foot of a wearer. The upper 102 retains the shoe 100 on the foot when the shoe is in use. Other features include an optional gel insole 110 for the wearer's comfort. The upper 102 may be coupled directly or indirectly to the sole, for example, by stitching 112 and / or gluing 114.

[0027]The shoe 100 also includes a heel assembly 116 including a housing 118, a heel piece 120, and a pivoting latch mechanism 122 that is located on the lateral side of the shoe. Thus, a button 124 of the pivoting latch mechanism 122 is located on the outer side of the left foot, the right shoe being a mirror image of shoe 100. The heel assembly 116 may be attached to the outsole 132, for example, by the use of machine screws, gluing, nailing, ri...

second embodiment

[0038]FIG. 7 shows a dual use heel assembly 700 constituting what is disclosed. The heel assembly 700 is shown in a series of configurations 702 including an extended high heel configuration 704 in which heel piece 706 is fully rotated and locked into a radially outboard location, a pivoting configuration 708 in which the heel piece 706 is unlocked and movable 710 towards the receptacle 134 of housing 118, and a retracted configuration 712 in which the heel piece 706 resides within receptacle 134 of the housing 118. The heel assembly 700 is identical to the heel assembly 116 as shown in FIG. 1, except for differences in the heel piece 702 as compared to the heel piece 120 of FIG. 1. Specifically, heel piece 702 differs from heel piece 120 in that heel piece 702 has a first top cap 714 which is hidden from exterior rear viewing when the heel assembly 700 is placed in the extended high heel configuration 704. This contrasts with the top cap 140 of FIG. 1, which is visible from the rea...

Abstract

A dual use women's shoe has a pivoting heel assembly. The heel assembly has a housing and a heel piece. pivoting is controlled by use of a two stage bayonet latch that may be selectively manipulated to convert the shoe between a ladies court style with the heel fully extended as a high heel and another style of lesser height with the heel piece in a retracted positon down beneath the sole. The other style may be a wedge, loafer, mule or sandal. The heel assembly may include with a spring that biases the heel piece towards the fully extended high heel configuration, such that the retracted heel piece in the retracted configuration springs into the fully extended high heel configuration when a button of the bayonet latch is depressed.

Description

RELATED APPLICATIONS[0001]The present application claims benefit of priority to U.S. provisional patent application Ser. No. 62 / 541,878 filed Aug. 7, 2017 and is a continuation-in part of U.S. design application No. 29 / 618,297 filed Sep. 20, 2017, both of which are hereby incorporated by reference to the same extent as though fully replicated herein.BACKGROUNDField[0002]The presently disclosed instrumentalities relate to women's footwear and, more particularly, high-heel shoes with a heel that may be collapsed into a walking heel.Description of the Related Art[0003]Women's footwear are an integral part of fashion. Both high heels and flats are widely used. Most women prefer to have both styles of shoes for different occasions. United States patent publication 2015 / 0113837 to Isinhue et al. shows a dual use women's shoe that has a pivoting heel, such that a single shoe may be placed into a high-heeled configuration or, alternatively, that of an intermediate heel. The intermediate hee...
